History

History of the Laboratory for plasma and radiation/surface interaction, created together with the Institute, is indissolubly connected with development of the experimental base for solving the issues of aerodynamic heating re-entry hypersonic vehicles. In order to meet these issues the four inductive RF-plasmatrons had been constructed: IPG-1 (1963 - 1977), IPG-2 (1977 - 1989), IPG-3 (1984 - :) and IPG-4 (1989 - :). M.I. Yakushin, who had been managering the Laboratory since the first day until November 2001 put the two fundamental principles. The first one: to have the two facilities - R&D facility for investigations of plasma/material interactions physics and another one, more powerful engineering facility for testing elements of the thermal protection. That principle was realized in facilities IPG-4 and IPG-3. The second principle: joint work of the experimenters and theorists in order to accurately extrapolate the results of material testing to the hypersonic flight conditions.

In the laboratory have been studied and tested practically all the thermal protection materials developed at NPO "Energy" and "Molnia" for different space vehicles. The laboratory was engaged in the State program "Buran". At the first time the catalytic properties of the thermal protection materials with respect to atomic recombination were determined. Multicyclic (up to 100) testing thermal protection tiles of the "Buran" vehicle at the conditions, which simulate aerodynamic heating and material oxidation, were carried out.

In the frameworks of international ISTC and INTAS projects the theory and technical approach for simulation of thermochemical plasma/surface interaction for entrees of space vehicles in the Earth and Mars atmosphere were developed. At the last time in collaboration with ONERA (France) and VKI (Belgium) in the IPG-4 plasmatron catalytic properties and oxidation process of SiC material for trajectory parameters of European experimental space vehicles Pre-X and EXPERT were studied.

Up to now exploitation of RF-plasmatrons has confirmed correctness of technical and engineering solutions undertaken. At the present time the team and both facilities are claimed by Russian aerospace industry.
